Lydia's chewing on her bottom lip when she holds her arm up for Steve. The initial motion is familiar; it's what she's been doing on his throat. As he explains and demonstrates, Lydia realizes that she'd been right all along about this particular lesson. It's meant to crush the windpipe. The idea of it makes her sick to her stomach, but she understands why he's showing her. There's an empowerment to knowing how to do something like that if the need arises.
